Certain features of the apparatus illustrated in the above referred todrawings and described hereinafter are disclosed and claimed in theapplication of Olgierd Gierwiatowsky, application Serial No. 441,624,filed May 4, 1942. These features include a record transfer mechanismwherein the transfer of records from one position to another areeffected by a single record edge engaging transfer 'arm, theconstruction whereby the said arm is actuated from a cam,

and the arrangement for centering and clamping a record in playingposition.

Referring to the drawings, the reference numeral 48 designates a basewhich may consist of an integral casting which provides a support for amotor 4| and a record magazine 42. The base comprises six downwardlyprojecting legs 43 (only four of which are shown in dotted lines inFig. 1) whereby the machine may be supupon which the movable unit 48 issupported.

The rail formation 45 is recessed to receive a.

.ciently resilient to serve in place of universal Joints. A small pieceof flexible shafting may also be employedat 56. The end of the shaft 55remote from the motor, which portion of the shaft is indicated by thereference numeral 51, is provided with bearings in abracket 58, which ismounted on a platemember 59, rigidly bolted to the base 48. Between thetwo bearing portions of the bracket 58, the shaft 51 freely supports ahelical pinion 68, and has rigidly mounted thereon a disc 6|. The disc6| carries a pin 62 whichis directed towards the pinion 66. This pinserves as an anchorage for a spring clutch member 63, several turns ofwhich embrace a cylindricalhub member64, which is integral with thepinion 60. The spring clutch member 63 is arranged so that the drive ofthe motor tends to release the spring clutch member. Thus,'in normaloperation of the machine, the motor will drive the mechanism, but if,for

' any reason, the mechanism becomes overloaded,

the spring clutch member 63 will slip and the rotate without driving thepinion 60.

The pinion 66 meshes with which is rigidly mounted on a shaft; 66 (Figs.4 and-5). The shaft 66 is arranged in eccentric relation to the gear 65and it is surrounded by an eccentric sleeve 61, which is adapted to berigidly secured to the shaft.66. the outer end of the haft 66 isprovided with a reduced threaded end 66 .which is adapted to receive 'anut 69. A washer 10 bears against the outer end ofthe sleeve 61, and alock washer 1| is interposed between the nut 69 and the Washer 16. Itwill readily be understood with reference to Fig. 5 that by merelytightening the nut 69, the sleeve 61 may be immovably secured to theshaft 66. Thesleeve 61 is provided near its outer end with a flange 12,which serves to hold the the helical gear 65,

assembly in an elongated bearing 13 mounted on the plate member 59 (seeFig. 4). The outer end of the sleeve 61, that is, the portion beyond theflange 12, is provided with flat faces 14 (Fig. "1) whereby the sleeve61 may be rotated relative to the shaft 66 so as to provid any desireddegree of eccentricity between, the outer surface of the sleeve 61 andthe gear 65. When such an adjustment is made. the nut 69 is of courseloosened, and after the desired adJustment is made, the nut 69 istightened so that the gear 65 is provided with a definite desired degreeof eccentricity relative to the bearing 13. The purpose Of thiseccentricity will be hereinafter more fully explained.

For this purpose,

of the shaft 88 and the eccentricity of the sleeve 51 should be veryclosely the same so that in at least one position of the sleeve 81 onthe shaft 88, the outer surface of the sleeve 81 may be in concentricrelation to the axis of the gear wheel 85. r

A splined shaft 15 is secured to the gear 85 so as to extend axiallytherefrom away from the shaft 88. This splined shaft 15 extends inwardlyof the machine over the rack 48 (Figs. 1, 2 and 3). Its extremityadjacent the gear wheel .85 is nonrotatably received in a disc 15, withwhich it has a splined connection (Fig. 5). The splined disc 18 is heldto the gear 85 by means of an annular member 11, which is mounted on thegear 85 by means of screws 18. The annular member 11 is provided with aninner flange 18 which is adapted to overlap the disc 18.' The side ofthe disc 18 adjacent the gear 85 is countersunk and receives a screw 88which projects beyond the shaft 15 so as to loosely anchor the shaft tothe disc 18. me disc 18 is secured to the annular member 11, andconsequently to the gear 85 against relative rotation by means of a setscrew 8I mounted in the annular member 11. It will readily be understoodthat by merely loosening the screw BI and rotating the shaft 15 relativeto the gear 85, that the eccentricityiresulting from the relativepositions between the shaft 88 and the sleeve 81 may be adjustedcircumferentially to any desired position relative to the shaft 15.After the desired adjustment is made, the set screw 8I is tightened.

On the opposite side of the base from the plate member 58 is mounted aplate member 82 (Fig. s

which is adapted to serve as an abutment for a member 83 on the movablecarriage. A bolt 84,

adjustably mounted on the plate member 58' serves as an abutment foramember 85, also mounted on the movable carriage.

The base 48 provides supports 88 for the reception of the magazine 42(Figs. 1 to 3 and 12) The magazine 42 comprises two end members 81, eachprovided with a flange at it lower end, which flange rests on one of thesupports 88. The end members are connected by a rear bar 88 shelfformation 88, which is inclined downwardly I and rearwardly towards themagazine, as best seen in Fig. 2. The two frame members 84 and 95 areassembled together in spaced relation by means of three bolts andspacing members 81, as best shown in Figs. 2 and 3. The supportingwheels 41 are mounted on the end members.

and 85. The carriage is movably secured tothe base by means of guidebars 88 which extend transversely of the machine and are rigidly securedat the lower ends of the frame members 84 and 85 by means of bolts 88.The guide bars 88 extend inwardly beneath shoulders I88 formed on therack 48, as best seen in Figs. 2 and 3.

A sleeve I8I (Fig. 9) located in alignment with the shaft 15, isrotatably mounted in the frame members 84 and 85. The splined shaft 15extends into the sleeve I8I through a splined member I82, with which ithas a spline connection.

.The member I82 is rigidly secured to the sleeve mechanism. As best seenin Figs. 9 and 11, this clutch mechanism includes an inner annularmember I85 which is integral with the gear I88, an intermediate annularmember I86 which is integral with the worm I84, and an outer annularmember I81. 'The. outer annular member is pro- (Fig. 12) provided with aseries of notches 88,

"each notch being adapted to receive a record. The forward extremitiesof the end members 81 are connected by a bolt 88 upon which aresupported a series of guide bars 8|. The guide bars iii are separated byshoulders 82, and the extreme guide bars are separated from the endmembers 81 by spacer members 88. The guide bars extend upwardly and areinclined rearwardly to a slight extent. Their upper ends are preferablytapered to a relatively sharp point so that the space between adjacentguides is relatively greater at their upper extremities. The spacesbetween the guide bars 8I are located in alignment with the notches 88.The guide bars 8| are preferably of fiat stock, their width beinglocated in the longitudinal direction of the machine.

The remaining mechanism of the machine is mounted on the carriage 48,previously referred to. This carriage comprises two main frame members84 and 85. The main frame member 84 is vertically disposed and 'consistsof a casting of substantially rectangular form, as shown in Fig. 3. Themainframe member 85 is likewise in the form of a casting and ipreferably of substantially triangular form, as shown in Fig. 2. Theframe member 85 is,-how ever, stepped at an intermediate height in themanner shown in Figs. 1 and 4, the stepped portion providing a videdwith one ormore peripheral recesses I88 (Fig. 11) whereby its rotationmay be arrested by a detent I88 (Figs. '19, 20, and 21) in a mannerwhich will be more particularly described hereinafter. The outer annularmember I81 is provided with an interior projection II8 which extendsinto a slot in the annular member I88, as best seen in Fig. 11. Betweenthe projection II8 and the sides of said slot are pockets III whichreceive the out-tumed ends of a coil spring II2 which naturally coilstightly around the annular member I85. As shown in Figs. 9 and 11,clearance is provided between the annular members I85 and I88 to providefor the location and limitedexpansion of .the spring I I2. When theannular member I81 is allowed to rotate freely, then whenthe shaft 15 isrotated in one direction or the other, then the gear I83 and the worm mwill rotate in the same direction. Thus, if the pinion I83, and ofcourse its annular member I85, is rotated in the clockwise direction, asviewed in Fig. ll, then the spring H2 is tight upon the annular memberI85, and theright hand end of the spring, as viewed in Fig. 11, willengage the annular member I84 so as to rotate this member also in thesame direction. When, however, the annular member I81 is held againstrotation, in the manner previously indicated, then the annular memberI88 is carried in the clockwise direction away from the right hand endof the spring I I2 so that the tendency to drive is exerted by the lefthand side of the spring I I2 against the projection II8. In thisrelation, the rotation of the member I85 tends to loosen the spring sothat the clutch connection between the worm I84 and the gear I85 issubstantially disengaged. It will be understood that a precisely similareffect takes The helical gear I03 meshes with ahelical gear II5 on adrive shaft II6 (Figs. 3 and 8). The shaft 6- is mounted in suitablebearings II'I which are carried by the frame member 94. Adjacent itsupper end, the shaft H6 is provided with a helical gear II8 which mesheswith a helical gear H9, freely mounted on the turntable shaft I20. Thehelical gears I03, H5, H8, and III! are of the same diameter. Atanintermediate position, the shaft II6 carries a worm I2I which mesheswith a worm gear I22 which is freely rotatable on a cam shaft. I23 whichextends between the frame members 94 and 95, as shown in Fig. 27.

The shaft I20 is rotatably mounted in suitable hearings in the framemembers 94 and 95, as

shown in Figs. 4 and 16. Between these frame members and alongside thegear I I9, the shaft I 20 rigidly carries a fly wheel I24. Upon the hubI25 of the gear H9 is mounted a coil spring I26 which is of such a sizethat it grips the hub I25.-

The ends of the spring are turned outwardly, as shown in Fig. 4A so thatone or other of these ends tends to contact a pin I21 carried by the flywheel I24. The arrangement is suchjhat when the hub I25 is driven in onedirection, then one of the ends of the spring I26 engages the pin I21,and this engagement is such that it tends to release the spring I26 fromthe hub I25. The spring is sufficiently strong that this release doesnot ordinarily take place, but the turntable elements and the fly wheelI24 are driven through the engagement of this end of the spring I26 withthe pin I27. -As will hereinafter appear, the turntable I24 is driven inopposite directions. It will be seen that when the direction of rotationis reversed, then the other end of the spring I26 is brought intodriving operation. This connection, and also the previously describedsimilar connection 62 and 63 between the motor shaft and pinion 60, areeffective in suppressing high frequency speed fluctuations which mightotherwise affect the quality of the musical reproduction.

One end of the shaft I20 projects through the frame member 95 andcarries a turntable element I28 which is adapted to engage the record atits center. This turntable element is so small that it is clear of threcorded surface on substantially all records. As best seen in Fig. 4,the turntable element I28 is located immediately on the outer side ofthe frame member 95 at a position substantially above the shelf portion96 of that frame member. As best shown in Fig. 16, the end of the shaftI20 which carries the tumtable element I28 is provided with an axialopening I29 which is adapted to receive a pin I30 which projects. out ofa movable turntable element I 3|. The pin I30 has an outer tapered endI32 which is'adapted to project into the opening I 29 when a record I 33is held between the turntable elements I28 and I3I, as shown in Fig, 16.The turntable member I 3I is rigidly secured to the pin I 30 to which itmay be secured by a pressed fit. The pin I30 is rotatably mounted in anopening I34 in a block I35 in which it is secured against removal by anysuitable means, for example, by means of a circumferential groove and aset pin I36. The inner end of the pin I 30 comprises a ball I 3'! whichis adapted to bear against the inner end of the opening '34. The block I35 is pivotally mounted by means of a pivot I38 between the bifurcatedupper ends I39 of an arm I40. Th pivot I38is located obliquely, as shownin Fig. 2, so-that the block I35 is mounted to swing in a plane whichincludes numeral I43. The two arms I39 are bridged by a plate I44 whichcarries a set'screw I44. set screw is adapted to engage the block I35 inthe manner shown in Fig. 17, and by use of this set screw, the pin I30can be adjusted accurately to cooperate with a record I33 which is to beloaded onto the turntable element, and with the recess I 29, in a mannerwhich will now be de-- scribed.

It will be understood that the record elevating arm I45 which carriesthe record elevating member I42 is swung into the position in which itis shown in Fig. 2 in order to elevate a record from the magazine intoloading position. When a record is thus elevated, it rolls up th shelfportion 96 of the frame member- 95. This shelf a portion is providedwith a groove I46 (Figs. 1

- swung inwardly towards the turntable element I28, as shown in Fig. 18.Continued movement and 16), preferably lined with a flexible member I41,so as to guide the record while it rolls up the shelf portion 96. Whenthe record is thus elevated into a position in which it is shown in Fig.2, its central opening I48 is so located that the point of the pin I30enters just below the top edge of the opening I48, when the arm I is ofthe arm I40 towards the turntable element I28 first raises the recordand then brings the conical extremity. I32 ofthe pin. I30 into the- 3opening I 29 in the manner shown '18.

Continued approach of the arm I40 towards the turntable element I28causes the pin I30 and the block I 35 to swing about its pivot bothupwardly and away from the record elevating element I42 so thatlwhen thepin I30 is in alignment with the opening I29, the record I33 is clearboth from the lining M1 in the groove I46 and from the record elevatingelement I42. Continued movement of the arm I40 towards the turntableelement I28 finally clamps the record I33 between the twoturntableelements I 3| and I28, as is shown in Fig. 16. The arm I40 ismounted on a pivot I49 .supported in suitable bosses on the frame memberbelow the shelf portion 96 thereof. Also supported on the pivot I49 is abell crank lever I 50. This lever comprises an arm I5I which extendsinwardly, as shown in Fig. 16, and carries at its innermost end a. cam

roller I52 which cooperates ,with a cam I53, which will hereinafter bemore particularly described. The other portion of the bell crank leverI50 comprises a yoke I 54 (Figs. 2 and 16),

the upper portion of which is in alignment with the arm I40, and isprovided with an opening/ I55 through which projects a bolt I56 carriedby the arm I 40. The outer end of the blot I 56 carries a nut I51 whichlimits the outward movement of the yoke I 54 awayfrom the arm I40; Acoil spring I58 is located around the bolt I56 and bears against the armI40 and the yoke I 54 in the manner shown in Fig. 16. Spring means I59are provided which tend to move the arm I40 outwardly away from theturntable element I28. It will be understood that the cam I53 is adaptedto throw the yoke member I54 inwardly, that is, towards the frame member95, and this inward movement applies resilient force through the springI58 upon the arm I40 so as to cause it to engage the record I33 inloading position, raise it, and finally hold it between the turntableelements I3I and I28, as has previously been described. When the cam I53is moved to another position, the spring I59 moves the arm I40 away fromthe turntable element I28. In order to prevent any tendency of therecord I33 to move outwardly with the pin I30, I provide a. recess I60in the face of the I3I which is directed towards the turntable elementI28. In this recess 1 mount a spring I6I of fiat stock. When the springI6I is in engagement with a record I33 in playing position, as shown inFig. 16, the spring I6I is in the form of a spiral, the outerconvolution being secured to the turntable element I3I. When the turntable element I3I is displaced from the tumtable element I28, as shownin Fig. 17, the spring I6I is expanded outwardly in the form of aconical helix. This spring is relatively weak, since it need only bestrong enough to insure the removal of the record from the pin I30.

The cam I53, a cam I62, and a disc I63 are rigidly secured together toform an integral cam assembly which is mounted on the shaft I23, asshown in Fig. 27. The disc I63 is located adjacent a notched wheel I64mounted on the hub of cam unit is separated from the notched wheel I64and the hub of the gear I22 by a washer I65. The disc I63 has pivotallymounted thereon a dog I66 (Figs. 19, 20, and 21) which has a detent I61which is adapted'to enter any of the notches of the notched wheel I64.Means, such as the spring I68, are provided to bias the dog I66 towardsengaging relation with the notched wheel I64. The dog I66 is providedwith an elongated tail I69, which is located in transverse alignmentwith a recess I10 formed in the disc I63, as is shown in Figs. 19 and20. The dog I69 is adapted to be held out of engagement with the notchedwheel I64 by means of a pin I1I carried by an arm I12, as shown in Fig.19, or by a member I12 carried by an arm I13, as shown in Fig. 21. Whenthe dog I66 is not engaged by either the pin I1I or by the member I12",the detent I61 is forced into engagement with the notched wheel I64 withthe result that the cams I53 and I62 are driven from the gear wheel I22.The pitch of the worm I04 is such that each half revolution of this wormcorresponds to a translation of the carriage 48 through a distance equalto the distance between centers of adjacent record pockets in themagazine 42.

As best seen in Figs. 19 and 23, the detent I09 associated with clutchcontrol member I01, previously of the lever I13, also previouslyreferred to. This lever carries at its upper end the contact member I12which is in alignment and adapted to cooperate with the disc I63. Thelever I13 is rigidly mounted on a shaft I" (Fig. 23), supported bytheboss formedon the frame member 94. On the outer side of the member I18is freely mounted on the shaft I11. The member I18 is held in positionby means of a collar I19 (Figs. 3 and- 23), which'is keyed to theshaftI11. The collar I19 carries diametrically opposed radial pins I80and I". The pin I80 is located between laterally projecting pins I82 andI83 (Fig. 3) carried by the member I18, said pins being adapted toengage the pin [80. The member I18 is biased in clockwise direction, asviewed in Fig. 3, by means of a spring I84. The collar I19 and the shaftI11 are biased in which is rigidly. the gear wheel I22. The

referred to, is carried on the lower end.

frame member 94 a turntable element counterclockwise. direction, asviewed in Fig. 3, and consequently the arm I13 is biased in thecounterclockwise direction, as viewed in Figs. 3, 19, 20, 21, and 22,bymeans of a spring I9I connected to the pins I8I and I83, with thecontact member I12 in engagement with the disc I63. When the pin "I hasraised the detent I61 of the dog I66 away from the notched wheel I64, asshown in Fig. 19, a condition which exists during the playing of arecord, the contact member I12 bears against the disc I63 and the detentI09 is located within one of the notches I08 so that the worm I04 isheld stationary. In this relation the record elevating member I42 i inalignment with one of the record spaces of the magazine 42. At'thistime, also, the member I18 is in the position in which it is shown inFig. 3, being in latching relation to a latch member I pivotally mountedon the outer side of the frame member 94. Themember I18 is moved intolatching relation by means of a cam member which engages a projection Ion the member I13. The cam member I89 is rigidly mounted on the outerend of a shaft I81. The shaft I81 is ing this member to move clockwise,as viewed in I Fig. 3, under the influence of the spring I84. As willhereinafter be explained, before this release takes place, the shaft I81is moved in the counterclockwise direction, as viewed in Fig. 3, so asto provide clearance between the cam I89 and the member I90for thisclockwise movement of the member I18. This clockwise movement of themember I18 brings the pin I82 into engagement with the pin I80, thusbiasing the shaft I11 in the clockwise direction, as viewed in Figs. 3,19, 20 and 21. Consequently, the detent I09 is pressed against thesurface of the annular clutch control member I01. When one of therecesses I08 is presented thereto, the detent enters this recess and thedrive of the worm I04 is terminated. It may here be noted that therelease of the member I18 occurs when the member H2 is holding the dogI66 out of engagement with the notched wheel I64 in the manner shown inFig. 21. Consequently, the release of the member I18 not only terminatesthe rotation of the worm I 04, but it also initiates the drive of thecam assembly, including the cams I53 and I62 and the disc I63, in onedirecto the member I12. While the cam assembly is thus rotating, themember I18 is in latched condition and the shaft I11 is biased in thecounterclockwise dirction, as viewed in Figs. 3, 19, 20, and 21, by aspring I9I. Consequently, when the recess I10 arrives in alignment withthe contact member I12, this member moves into the recess and swings thedog I66 away from the notched wheel I64. At the same time the detent I09is withdrawn from the notch I08 and the drive of the worm I04 isresumed. r

The record lifting member I42 is inthe form of a small disc carried atthe outer end of the.

ing arm I45 is rigidly mounted on a hub member- I92 which includes agear member I93 (Fig. 25). The hub member I92 is rotatably mounted on ashaft I94 extending between the frame members 94 and 95 for freerotation, and it is held in position by means of a spacing sleeve I95,also mounted on the shaft I94. It may here be remarked that the recordelevating member I42 is in alignment with the playing position of therecord on the turntable members and with the center of the groove I46 inthe shelf portion 96 of the frame member 95. The gear member I93 mesheswith a sector member I96 which is freely mounted by means of a boss 200on the shaft I81 (Fig. 25) Rigidly mounted on the shaft I81 is an armI91 which extends upwardly and carries a cam roller I98 which engagesthe cam I62 (Fig. 24). As previously indicated, the spring I89 biases.the shaft I81 in the clockwise direction, as viewed in Fig. 24, so thatthe roller I98 follows the cam I62 at all times. A sleeve I99 rigidlymounted on the shaft I81 has a pin 20I projecting radially into the pathof a pin 202 carried by the sector I96. When a record is being played,the sector I 96 bears against a set screw 202 which is mounted on anextension 203 of one of the guide bars 98 (Fig. 19). The sector isbiased downwardly into this position by means of a strong spring 204which is connected to the extension 203 and to a pin 205 carried on thesector. This pin is sufiiciently strong to enable it to lift the arm I45and a record from the magazine. During the playing of a record, the camroller I98 is located at the lowest dwell point I62 of the cam I62, asshown in Fig. 24, and there is a substantial clearance between the pins20I and 202 at that time. Two arms 206 and 201 are freely mounted on theshaft I81 and extend away from the sector I96 in parallel spacedrelation, as shown in Fig. 25. The arms 206and 201 are rigidly connectedby bars 208 and 209 so that they swin in unison as a frame around theshaft I81. A pin 2I0 carried by the arm I91 extends below the arm 201 sothat the arms 206 and 201 are elevated, as shown in Fig. 24 when the camroller I98 is located at the dwell I62 of the cam I62. A spring 2I Iconnects the arm,201 to the arm I91v so that counterclockwise movementof the arm I91 causes the arms 206 and 201. to move downwardly. When,however,'the arms 206 and 201 are arrested in a manner. which willhereinafter be described, the arm I91 is ableto continue its rotation inthe counterclockwise direction, as viewed in Fig. 24. It may be addedthat when the arms 206 and 201 are thus arrested,

the pin 20I engages the pin 202 and the sector I96 is rotated in thecounterclockwise direction, as viewed in Fig. 24, so that the arm I45 isswung in a direction to return a played record to the magazine. It maybe here noted that the arms 206 and 201 effect the raising of theplayer, arm away from the record, and that the return of the record tothe-magazine is effected after thetone arm is thus raised.

The latch member I86 is adapted to be released from the member I18 bymeans of selector levers 2I2 which are pivotally' mounted below themagag zine, as shown in Figs. 3 and 12. Two levers 2I2 are provided foreach record in the magazine, these levers being provided with upwardly.di-

rected projections2'l3, which are alternately displaced. .The levers arenormally held in lower position by meansof individual springs 2 I4 whichengage notches in the ends of levers adjacent the projections 2I3. -Intheir lower position, the levers v2I2 restupon a plate 2| 5 whichservesas a support,for lever operating solenoids 2| which are located on theunder side of the plate 2I5. 2I2, and, when a solenoid 2| 6 isenergized, its

armature moves upwardly and displaces the corresponding lever 2I2upwardly so as to bring its projection 2I3 into operative relation witha dog 2I1 (Fig. 3).- The dog 2" is pivotally mounted on the end of anarm 2I8, which is integral with the latch I85, and upon a horizontalaxis which is oblique relative to the direction of'travel of thephonograph carriage and also to the longitudinal direction of theselector levers 2I2. The

dog 2I1 normally hangs downwardly, and in its normal position, it mayengage either series of projections 2I3 depending upon the direction ofmovement of the carriage. If these projections are in their normalposition, the dog 2I1 is merely displaced, as shown in Fig. 3. If,however, a projection H3 is in elevated position, then the dog 2I1 isswung until it contacts either of two stops 2I9' carriedby the end ofthe arm -2I8, and the arms 2I8, I85, swing counterclockwise, as viewedin Fig. 3, against the action of a spring 220', thus unlatching themember I18. The arm- I then contacts a stop 22!, and further movement ofthe carriage causes the dog 2I1 to move the actuated lever 2I2downwardly towards its initial position. Its complete return to initialposition is effected by the engagement of a spring 2 withthe cam shapedsurfaces at the end of the lever.

Each solenoid 2 I 6 is controlled by an individual selector switch 2I9(Fig. 3), each of which may be actuated by its selector button 220. Itwill be understood that when the appropriate selector button is pressedinwardly, the switch 2I9 is closed and the corresponding solenoid 2I6 isenergized so that the corresponding bar M2 is pressed upwardly so as tobring its end into operative relation to the dog 2I1. It will beunderstood that the circuits of the solenoids and'the motor 4I may becontrolled directly by manually operable switches or that they may becontrolled by coin actuated means. I

It will be understood that two levers 2I2 are provided for each record.Thus, for twenty records, forty levers 2I2 are provided. Owing to theswinging of the dog 2", the two levers 2I2 corresponding to one recordare displaced sideways, and the two series of levers 2I2 correspondingto the playing of one side of the records, say the left hand side, andthe series corresponding to the playing .of the other side of therecords, say'the right hand side, are displaced sideways. As shown inFig. l, the displacement of the levers 2I2 for one particular record'istwo and one-half times the record spacing. Fig. 1, the first lever 2I2corresponds to the playing of one side of the first record, the secondOne solenoid 2I6 is provided for each lever- Ccnsequently,'reading fromleft to rightin record, and so on.

8 lever 2I2 corresponds to the playing of the same side of the secondrecord, the third lever 2I2 corresponds to the playing of the same sideof the third record, the fourth lever 2I2 corresponds to the playing ofthe opposite side of the first record, and the fifth lever 2I2corresponds to the playing of the first said side of the fourth Thefirst three levers 2I2 at each end have magazine record spacing. Theotherievers 2I2 have half this spacing and are arranged alternately forplaying opposite sides of records. The dog 2" is swung, as haspreviously been explained, so as to cooperate with one series of levers2I2 when the carriage is moving in one direction, and is swung tocooperate with the other series of levers 2 I2 when the carriage ismoving in the opposite direction.

The pickup 22I' is carried by a player arm 22I with its smallestdimension substantially Derpendicular to the plane of its record playingposition (Figs. .3 and 4), and is provided with a double pointed needle222 which extends through the pickup and is held in place by a set screw223. The doubl pointed needle 222 is located in oblique directionrelative to the longitudinal direction of the player arm 22I. The needle222 is arranged so that it forms an acute angle with the approachinggroove .of the record. Thus, when the right hand point of the needle isoperating, as shown in Fig. 4, the direction of -rotation of the record224 is clockwise, as viewed from the left in this figure. When, however,the left hand point of the needle 222 engages the record, the player arm22I occupies a position to the right of the record 224, as viewed inFig. 4, and the direction of rotation of the record is counterclockwise,as viewed from the left in Fig. 4.

In the embodiment of the invention shown in Figs. 1 to29, the player arm22I extends through a ring 225 (Figs, 2 and 29) which is provided withtwo pivot points 226 held in adjusted position by means of set screws.The pivots 226 cooperate with a block 221 resiliently mounted withinthev arm 22I. The block 221 is carried by springs 228, the ends of whichare rigidly mounted within and to the interior of the player arm 221.They may, as shown in Fig. 29, be anchored at 229 to a hollow orU-shaped block 230 contained within the hollow player arm, 22], andtheir opposite ends may be bent around away from each other to provideU-shaped portions 23I, which are also rigidly secured to the block 230.The axis provided by the pivot members 226 is parallel to the playingplane of a record supported on the turntable elements I28 and I3 I. Andthey are maintained in this relation by the support of the ring member225 on an axis which is parallel to the axis of the turntable elements.The player arm 22I projects downwardly beyond the axis provided by thepivots 226, and it is provided with a counterweight 232 (Figs. 2 and26') which accurately locatesthe center of gravity of the playerarm onthe axis of the pivots 226. Adjacent the weight 232, the arm 22I carriestwo rollers 233 which are adapted to be engaged by inclined or camsurfaces 234 on the arms 206 and 201. Thus, referring to Fig. 26, itwill be understood that when the arm 22I is adjacent the arm 206, thenthe player arm is located so as to cooperate with the back side of therecord, as viewed in Fig. 19 or the left side of a record as viewed fromthe front of the machine. when the arm 206 is elevated above itsposition shown in Fig. 26, the player arm 22I is biased by a spring 235so as to apply the appropriate side of the needle against the record.When the arms 206 and 201 are moved downwardly, in a manner previouslydescribed, the inclined surface 234 of the arm 206 engages the left handroller 233, as viewed in Fig. 26, and the arm 22 I' is swungcounterclockwise, as viewed in Fig. 26, to a slight extent, so that theneedle 222 is moved away from the record to a slight degree. When,however, the needle 222 is located to cooperate with the other side ofthe record, that is, the adjacent side, as viewed in Fig, 26, the arm22I occupies a position adjacent the arm 201. Under these circumstances,the spring 235 is relieved of its tension and the spring 236 iste'nsioned so that the arm 22I is biased towards that side of therecord, that is, the adjacent side, as viewed in Fig. 26. when the arms206 and 201 are elevated, the needle 222 engages that side of therecord. When, however, the arms 206 and 201 are moved downwardly, in themanner previously described; the cam surface 2340f the arm 201 engagesthe right hand roller 233, as viewed in Fig. 26, with the result thatthe arm 22I is swung around the pivots 226 to a slight degree in theclockwise direction, as viewed in Fig. 26, so that the needle is raisedor displaced away from the face of the record with which it has beencooperating.

The spring 235 is connected to a plate 231 and the spring 236 isconnected to a similar plate 238. The plates 231 and 238 are rigidlyconnected by means of rods 233, 240, and 2 to constitute a rigid frame.The rods 239, 240 and 24I are best illustrated in Figs. 1, 4, 19 and 20and particularly the latter where they are shown in section and fromwhich their location relative to the lates may be readily ascertained.This frame is pivotally mounted by means of opposed pivots 242 carriedby the frame members 94 and 95 on an axis which is parallel to the shaftI20 01' the turntable element I28, and consequently at right angles tothe axis provided for the player arm 22I by the pivot members 226. Thering 225 i integral with a'block 243 which is slidably mounted upon thebars 240 and 2 (Fig. 19). The block 243 can be slid along the rods 240and MI so as to locate the ring 225 adjacent the plate 238, as'

shown in Figs. 1 and 4, to adapt the player arm 22I for playing the lefthand' side of the record, as viewed in Fig. 1, or it can be slid towardsthe plate 231 to effect the playing of the opposite side of the record.The block 243 carries a formation 244 which is arcuate with respect tothe axis provided by the pivots 242. This formation 244 extends into agroove 245 and a sleeve 246, which is adapted to be displaced in amanner hereinafter to be described, in a direction parallel to the axisprovided by the pivot 242.

The mechanism carried by the pivots 242, that is. the frame includingmembers 231, 233, 239, 240,24I, together with the player arm 22I andelements carried thereby, needle 222, counterweight 232, ring 22.5, andthe block 243, are counterbalanced by a counterweight 241 (Figs. 4 and26) carried by plate 231 so that the center of gravity of this system islocated on the axis provided by the pivots 242. Thus, the player arm HIand associated elements are counterbalanced for movement about the axesparallel to and perpendicular to the shaft I20 which carries theturntable element I28. The rollersv 233 are located so that they lie inalignment with the pivots 242. Consequently, when the arm 206 or 201moves downwardly and cams the player arm 22I
